Cleaning-soaking in salt water-inflating, adding nitrifying bacteria, ammonia and nitrous acid, and turning into harmless nitrite. If the newly-built tank looks foggy, it means that the nitrification system has not been established, so it is suggested to add salt nitrifying bacteria. If there is no improvement, it is necessary to re-set the tank.

2. Raise water

A few days before changing water, it is best to put tap water in other containers and aerate it for a few days, and store the water to let harmful substances (chlorine and heavy metals) in the water evaporate. This is water cultivation.

3. Change water

In order to make guppies adapt to life faster, daily fish tank management is extremely important. Besides always paying attention to water quality and water temperature, we should also maintain the ecological balance in the fish tank. So it is necessary to use filters to purify sewage or change water.

The water used to raise guppies must be adjusted to a nearly neutral weak acidity or alkalinity (PH 6.5 ~ 7.5). If it is within this range, guppies can be raised without problems (it can be tested by PH test paper). Put in the dormant body of the filter bacteria, because after this bacteria is propagated, it is suitable for the water quality for raising guppies.

The water in the fish tank should be circulated frequently. The water is changed in a small amount and frequently, and every 2 ~ 3 weeks 1 time, with a quarter of the total water volume as the standard. The drastic change of water quality has done great harm to guppies. In addition, it should be cleaned at least once a year 1 time. Peacocks are still difficult to adapt to brand-new water, so it is necessary to keep about half of the old water to add new water.

Extended data

matters need attention

1, the fluctuation of pH before and after birth should not exceed 0.5.

2. After giving birth, the mother fish should be removed immediately or the mother fish may eat the fish larvae.

3. The young fish must be picked up and raised in a vat on the first 13- 14 day after birth.

4. After the parent fish is fished out of the breeding tank, it needs to be left alone for 1-2 days before it can be put back into the main tank.

5. The parent fish will continuously produce about 1 1 time, and there are few litters in 1 1 time, which will increase with the increase of body size.

6. The female fish can produce 22-25 times in her life, but after producing 1 1 times, she has to rest for a long time before she starts the second ovulation.

7. Leave the female fish alone for 3 days after delivery, and then put it back into the fish tank to avoid being chased by the male fish prematurely, which will affect the later reproductive quality.

8, breeding should pay attention to, don't stay in the same nest for more than three generations, so as to avoid continuous inbreeding lead to species degradation, make the offspring fish smaller and smaller, tail fin shorter. It is best to introduce the same species of fish for purposeful distant hybridization to prevent the degeneration of sub-species and achieve the purpose of improving species.
